How To Fix R8390 - Field &1 with reference field &2: Reference table &3 is replaced by &4

SAP Error Message - Details

• Message type: E = Error

• Message class: R8 - Messages from the meta data generation

• Message number: 390

• Message text: Field &1 with reference field &2: Reference table &3 is replaced by &4

What causes this issue?

The amount field &V1& from the view used for generation or from the
table has the currency/unit of measure field &V2& from table &V3&as
reference field.
To generate an extract structure, however, the currency/unit of measure
field is expected to originate from the same view or the same table.
Since the view or table used contains a currency/unit of measure field
&V2& with the same name, the reference to this field was changed in the
generated extract structure &V4& .

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Check if the reference adjustment is permitted, that is, if the
reference field assigned from the view or table really contains the
corresponding currency/unit of measure.
If that is not the case, you might be able to correct the unit reference
in a transformaton rule within BI. In this case, however, the data might
be displayed in the PSA incorrectly (decimal places).
